CNN: The Knack lead singer Doug Fieger, perhaps best known for the 1979 hit, "My Sharona," underwent successful brain surgery Thursday, his doctor reported.Fieger, 53, had two brain tumors removed during the operation at Cedars-Sinai Medical Center, publicist Guy McCain said.

Doug has been a friend of mine for about 12 years now and this news came as a shock. He's been an inspiration to me in many ways outside of music.

All the best, Doug.
